Sentinel Security
Detection and response built for teams that can't staff a 24/7 SOC.
About Sentinel Security
Sentinel Security gives small and mid-size companies the kind of threat detection and response that used to require a full security operations center. The platform watches endpoints, identities, email, and cloud accounts, correlates what it sees, and acts on threats automatically, with a human response team backing up the machines around the clock. More than 3,400 companies now run their security on Sentinel.
The company was founded in 2020 by former incident responders who kept getting called into the same situation: a 200-person company, breached weeks ago, discovering the damage only when ransomware detonated or a customer reported fraud. The tools to catch these attacks early existed, but they were priced and staffed for enterprises. Everyone else was left exposed. Sentinel was built to close that gap.
How the platform works
Sentinel deploys in hours: lightweight agents on endpoints, API connections to cloud and identity providers, and a mail integration that sits inline. From that moment, every signal flows into a single correlation engine.
- Endpoint detection and response across Windows, macOS, and Linux
- Identity threat detection covering credential abuse, impossible travel, and privilege escalation
- Cloud posture and workload monitoring for the major providers
- Email threat protection that catches phishing and business email compromise
- Automated containment that isolates compromised machines and revokes sessions in seconds
- A 24/7 human SOC that reviews, investigates, and calls the customer when it matters
Correlation is the difference
Individually, most attack signals look innocent: a login from a new location, a script execution, an inbox rule change. Attackers count on these events being reviewed in isolation, if at all. Sentinel's engine connects them: that new login, followed by that inbox rule, followed by that internal phishing email, is one incident, not three curiosities. The median time from first signal to containment across the customer base is eight minutes.
Why mid-size companies choose Sentinel
The companies most likely to be breached are the ones least able to staff against it. A full security stack with around-the-clock analysts costs more than most mid-size IT budgets entirely. Sentinel delivers the outcome, threats contained before they spread, at a price point that fits, with no security headcount required on the customer side.
In practice
A 300-person logistics firm had credentials phished on a Friday evening. Sentinel correlated the suspicious login with an unusual mailbox rule, locked the session, isolated the laptop, and had a human analyst on the phone with the customer's IT lead within twenty minutes. The attempted invoice fraud that followed bounced off an account that no longer existed.
Working with Hydra Labs
Hydra Labs repositioned the Sentinel brand and rebuilt the site around outcomes rather than acronyms, cutting the jargon that made security marketing impenetrable to the exact buyers Sentinel serves.
Our commitment
Contain threats in minutes, not the days it takes to notice them.
